Lou is super overtuned and needs to be nerfed.

For a long time before the buff, Lou was simply a B-C tier brawler mainly viable in hot zone. His position in the game absolutely did not warrant a buff as significant as the one he received, and if supercell wants to keep the reload time than some of his other Statistics need to be tuned down. He either needs a nerf to his super charge rate or a nerf to his freeze speed, because now that he can practically spew out projectiles without much need for coordination, the rates in which his kit was balanced around no longer make sense, and instead make for an insanely oppressive tank counter who still plays decently into non-tanks.
